Title: Protecting method for gate turn-off thyristor
Inventor: HIROSE MASAYUKI
IPC: H03K17/73
Filed: 1982-08-25
Abstract: PURPOSE:To effectively prevent the permanent damage of a GTO by bypassing an OFF pulse to another circuit when an anode current becomes abnormal during the energization of the OFF pulse. CONSTITUTION:The anode current of a GTO1 abnormally increases during the energization of OFF pulse of the GTO1, and when it exceeds the discriminated value of a current detector 4, the detector 4 outputs an OFF pulse inhibit signal. A gate control circuit 5 prohibits the energization of the OFF pulse by the OFF pulse inhibit signal. Simultaneously, when the OFF pulse inhibit signal is inputted to a thyristor 6, the thyristor 6 is fired, and the energy stored in the inductance of the OFF pulse passing route is bypassed through the thyristor 6 and circulated. Accordingly, when the detector 4 generates the OFF pulse inhibit signal, the current is immediately flowed to the GTO1 so that the OFF pulse becomes zero.

The light is received by the detectors 3. At this time, since the emitted light is polarized by the lens 4, the light passes through the defect even if the penetrated defect 5 is inclined and reaches the detectors 3 without fail. Thus the penetrated defect 5 can be detected accurately.

Title: Power unit for inverter
Inventor: UESUGI NAOYOSHI
IPC: H02M7/48
Filed: 1986-06-25
Abstract: PURPOSE:To improve a load efficiency by controlling a DC output voltage on the basis of an output frequency set value or a load state to set a PWM (pulse-width modulation) waveform having high basic wave content as an output voltage of an inverter. CONSTITUTION:When an AC input voltage is rectified to a DC voltage by a diode bridge 1, the DC voltage is detected by resistors 8, 9 in a detector 5, and input to a differential amplifier 10. An output frequency set value is input through a D/A converter 11 to the amplifier 10. An AC input voltage waveform is collected by a transformer 4, multiplied by the output signal of the detector 5 by a multiplier 6, and then input to a differential amplifier 7. The amplifier 7 compares the output from the multiplier 6 with the terminal voltage of a resistor 15, and applies a control signal through an inverting amplifier 14 to a transistor 2. Thus, the ON/OFF operation of the transistor 2 is controlled to obtain a stable DC output voltage.

Title: Powdery particle dividing and weighing device
Inventor: OSAKI YOSHIO
IPC: G01G13/08
Filed: 1988-06-15
Abstract: PURPOSE:To maintain the weighing accuracy by forming a vibrating feeder installed in an electromagnetic balance scale to be a ball feeder, and providing an acceleration sensor in said feeder thereby to control the vibration amplitude through feedback thereof. CONSTITUTION:An electronic scale 1 converts the measured weight of powdery particles 11 into the amount of electric signals and then transmits the same to a control unit 7. An acceleration sensor 6 changes the amplitude amount of vibrations of a ball feeder 4 into electric signals and transmits the same to the control unit 7. An electromagnetic mechanism 5a coupled below a storing unit 5 is repeatedly energized by the vibration voltage outputted from the control unit 7 and produces an up-and-down vibration to the storing unit 5 by the repulsive force of a plate-like resilient means 4b. When the measured weight of discharged powdery particles 11 reaches a preset value (x), the vibrating and oscillating operation of the feeder 4 is stopped because of the transmission of stop signals thereto from the control unit 7. Thus, the powder medicines can be divided and enclosed with the accuracy of about 10mg of the average deviation.
